A certain chemical reaction releases [tex]$39.1 \, \text{kJ/g}$[/tex] of heat for each gram of reactant consumed. How can you calculate the heat produced by the consumption of 3.3 kg of reactant?

Answer :

Final Answer:

The consumption of 3.3 kg of reactant would produce 128,730 kJ of heat.

Explanation:

To calculate the heat produced by the consumption of 3.3 kg of reactant, you can use the given heat release value of 39.1 kJ/g. The formula to calculate heat (Q) is:

Q = mass × heat release value

Where:

mass = 3.3 kg (converted to grams)

heat release value = 39.1 kJ/g

First, convert the mass from kilograms to grams:

mass = 3.3 kg × 1000 g/kg = 3300 g

Now plug in the values into the formula:

Q = 3300 g × 39.1 kJ/g

Calculate the heat produced:

Q = 128,730 kJ

So, the consumption of 3.3 kg of reactant would produce 128,730 kJ of heat.
